2.19 Winterizing

Failure to properly winterize the heat pump as needed may result in serious equipment damage.
DANGER
Deactivate power while routing wiring to control board.
l
Follow all National Electric Codes (NEC) and/or State and Local guidelines.
l
WARNING
Deactivate all electrical power to heat pump before performing hard freeze procedures.
l
NOTICE
Failure to winterize heat pump may result in serious equipment damage. Freeze damage is not covered under the
l
heat pump warranty.
While the plumbing connections are in the winterized condition (not fully tightened), it is imperative that water
l
not run through the heat pump. Loss of water through loose plumbing connections may result in damage to
circulation pump, pool and spa structures, and other equipment.
Light Freeze Conditions
A light freeze is when the ambient air temperature falls below 32 degrees Fahrenheit (0° C) for less than 8
hours. Typically during light freeze conditions circulating (or moving) water will not freeze. Temporarily
activate the filter pump for continuous operation during light freeze conditions. If the heat pump is directly
controlling a water circulation pump, any groups marked as requiring freeze protection will automatically
have water circulated to the equipment. See "Freeze Protection" on page 69.
